3 Claims.

The principal object of this invention is to provide a forced ventilator for toilet bowls that utilizes the flushing tube of the'bowl and which will remove all odors from the bowl. a

A further object of my invention is to provide a forced ventilator for toilet bowls that may be readily placed on installations now in use and which may be operated when the bowl is in use.-

A still further object of this invention is to provide a forced ventilator for toilet bowls that is uniform and direct in its application of Suetion for the removal of gases or fumes.

A still-further object of this invention is to provide a forced ventilator for toilet bowls that r canbe used on a number of installations in the same building. 7 A

A still further object of my invention is to provide a forced ventilator for toilet bowls that is economical in manufacture, durable and eflicient in use.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in whichf Fig. 1 is a side sectional view of a toilet bowl and water tank with my device installed ready for use. i

Fig. 4 is an enlarged sectional view showing the .method of installing my device on a common overflow pipe.

Fig. 5 is an enlarged side view of the valve float and air chamber illustrated in Fig. 4.

Every installation of a closet bowl, urinal, or the likehas an outside ventilator. However this is merely a pipe opening into the outside atmosphere and is not satisfactory. Several attempts have been made to attain forced ventilation by adding to the bowl or vessel some complicated type of external suction apparatus but, due to the complication of the device, they have not been satisfactory. These types were hard to install, did not present enough suctional area within the vessel, and were extremely limited in their adaptation to installations already in use. A distinct need is felt for a forced ventilator for toilet bowls and the like that will eiiiciently and completely carry off all" odiferous gases as they originate and expel these fumes into the outside atmosphere at some remote point. I have overcome the disadvantages herebefore enumerated and have supplied a solution for the need of an economical, compact, easily installed, and prac tical forced ventilator for bowls and the like as will be appreciated and as hereinafter set forth.

Referring to the drawing, I have used the numeral it to designate the ordinary toilet bowl having the integrally formed flush conduit ll about its top edge. The numeral l2 designates the ordinary toilet seat ring hingedly secured to the upper surface adjacent the rear portionof the bowl l0 and having the ordinary cover lid hinged thereto.

The numeral 3 designates a resilient gasket such as a rubber tube or the like which is secured to the seat l2 and which, when the seat is down, prevents air from entering the bowl Ill between the seat and the top of the bowl.

I have used the numeral It to designate the common water storage box. As is known, this box remains full of water to a predetermined level and is supplied with a' rubber ball release valve which I have designated by the numeral l5.

form of a horizontal S to form a water seal as shown in Fig. 2. This s-shaped portion I have designated by the numeral It. The numeral l9 designates the ordinary filler pipe which may flow intothe open end of the S-shaped pipe I8. As is generally ,known, the filler pipe I!) is for the purpose of. continuing a flow of water after the tank has been flushed which will run through the overflow pipe l1, and into'the bowl II) for preserving a water trap therein. The numeral 20 designates a ventilator pipe having one end in communication with the inside of the pipe l6 and having its other end in communication with a remotely positioned housing 2|. Secured within this housing is an electrical motor 22 which oper-v between oneside of a source of electric energy I and one side of the windings within the motor 22.

The numeral 26 designates a second electric wire having one end in communication with the electric motor 22, and its other end in communication with a suitable; switch 21. This switch 21 may be either of the manually operated type or may be automatically actuated by the hinge action when lowering the seat H. The other side of the switch 21 is in communication with the other side of a source of electric energy as shown in the drawing. Referring to Fig. 4 of the drawing, it will be noted that I have provided an alternate construction for the accomplishment oi the same specific purpose, but which utilizes the common overflow pipe located within the water chamber as a ventilator tube when it is not being used for the specific purpose of carrying water. This type, while being of practically the same utility, lends itself particularly to specific forms of construction. The overflow pipe has its inside passageway in communication with the inside of the pipe l6 below the ball valve l5 and has on its upper end an air chamber which I have designated by the numeral 28. The pipe 20 is secured to, and in communication between, the blower fan and the chamber 28 for sucking the air from the bowl l0 through the conduit II, the pipe IS, the overflow pipe l'l, through the chamber 28, and thence through the pipe 20, where it is expelled into the outside atmosphere by the fan 23. When using this type of construction, the pipe l9 will extend through the upper part of the housing 28 to be directly above the overflow pipe I1 and capable of discharging water into it. A portion of the lower surface of the housing 28 slopes upwardly and outwardly and has a hole cut therein to receive a valve plate 29 as shown in Fig. 4. The numeral 30 designates afloat arm which is rotatably mounted in the walls lo: the housing as and which has operatively secured thereto the valve 29.

The arm 30, external of the housing, is bent at right angles downwardly and outwardly and has secured to its end portion a float 31 as shown in Fig. 5. By the above construction it will be seen that normally the valve plate 29 will be closed and the air chamber between the bowl l0 and the fan-23 will be intact. However, should the tank ll become too full of water due to leakage, it will actuate the float 3| thereby rotating the arm 30 within the housing 28 opening the valve 29 to allow the excess water to overflow through the pipe H.

The practical operation of my device is follows: The pipe 20 is secured to the p'pe l6 and in communication with its inside passag away. When the switch 21 is closed, the motor 2. will operate thereby actuating the fan 23 and sul king air, uniformly, from the inside 01' the bowl l0 through the conduit ii. The gasket element l3 will prevent any air leak between the seat l2 and the top of the bowllll thus pulling air from the top thence through the conduit ll into the conduit it through the pipe 20, housing 2|, and expelling it through the pipe 24. When the bowl is flushed, the ball valve I5 is pulled upwardly in the usual manner allowing the water to come through the pipe IS, the conduit II, and thence into the bowl, after which the ball l5 drops back to its seat, and the tank I again fills with water. when it has reached the proper height, it is shut oil by the ordinary float valve, but some water flows, during the filling of the tank, through the pipe ls'for restoring the water inthe bottom of the bowl i0 should it be forced out by the force of the flushing action. This action of the pipe I! also fills one end of the svshaped member ll which efl'ectively seals it and prevents the blower fan 23 from pulling air out of the chamber l4. Thus the force of the suction is directed entirely upon the bowl It. The same is true of the construction illustrated in Fig. 4 except in this case a mechanical valve is pro- ,vided for the overflo'w and the overflow pipe have provided a forced ventilator for toilet bowls that is extremely easy to install, that is highly eiflcient in its use, and that does not interfere with the normal function of any portion of the system in conjunction with the toilet bowl. Furthermore, my device is inconspicuous and directs its force where it is most needed. It is positive in its operation, and has nothing that would become out of order being free of complicated mechanical parts.

My device may be easily used in multiple installation by merely tapping into the pipe 20 and using the same blower fan for all of the bowls. My device is highly desirable for use in public buildings where there is usually a lack of ventilation, andis particularly, adaptable to private homes.

1 while I have shown and described my device for use withtank reservoirs, it may also be used with delayed valve and automatic installations by tapping into the flushing conduit between the valve and the bowl for the utilization of the flushing conduit as an air suction conduit for the uniform extraction of gases from the vessel.

Some changes may be made in the construction and arrangement of -my improved forced ventilator for toilet bowls without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modifl'ed forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
